Provisioning: Add Windows 11 on ARM as non-blocking in CI

Visual Studio 2022 is the first msvc having natively support for
building and debugging ARM64 apps. [CI Platforms]

Provisioning needed to take new Get-CpuArchitecture
helpers.ps1 function into use in several installations.

Requirements for other branches
- Get-CpuArchitecture helpers.ps1 function
- Skip qtwebengine with Windows 11 ARM (QTBUG-124632)

List of excluded installations in Windows on ARM:

- Could be added later
  - MinGW - QTQAINFRA-6079
  - DirectX SDK for RTA
  - libclang
  - mcuexpresso
  - fbx for msvc2022
  - Ruby
  - For python
    - conan
    - emsdk

- Not supported yet
  - FFmpeg
  - Msys2 (for FFmpeg QTBUG-124399)
  - MySQL
  - PostgreSQL
  - Java JDK
  - Strawberry Perl
